Door-to-door canvassing remains an effective way for roofing companies to find new customers. A rep at the door can point out storm damage, offer a free inspection, and book an appointment on the spot. 

However, a D2D team comes with friction points that eat into profitability and make it harder to grow your business:

• Reps knock on a lot of cold doors. Many homeowners won’t be home when a rep comes by, and homeowners who do answer may have never heard of your company.
  
  

• Lead volume is capped by headcount. Each rep can only knock on so many doors in a day, so reaching more homes usually means hiring, training, and paying more reps.
  
  

• Some areas restrict door-to-door sales. Local rules may require your reps to get a permit or limit when and where they can knock.

One cost-effective option is to warm up neighborhoods with outbound text messages before your reps knock, then send reps to the homeowners who replied. 

At GlassHouse, we call this digital door knocking. Our software helps you reach homeowners who aren’t already in your CRM. One of our clients, Mighty Dog Roofing in Pittsburgh, used GlassHouse to sign $135,000 in roofing jobs after spending $6,500 over six weeks. That comes out to $197 per booked appointment.

In this post, we look at how you can use GlassHouse to make your D2D team more cost-effective, including a short walkthrough of how the software works, plus additional strategies for getting more from your sales team.

How to use GlassHouse to make your D2D team more cost-effective

GlassHouse is digital door knocking software that can help your sales team close leads more effectively by:

• Warming up homeowners before a rep arrives at their door

• Showing your team which homeowners are interested in your services

• Reaching homeowners in neighborhoods where door-to-door sales are restricted 

• Showing you which areas you’ve canvassed have produced signed jobs.

Below, we walk through how that works on the platform.

Warm up a neighborhood before your reps knock

If a homeowner has already received a text from your company before a rep knocks, the rep is following up on a message instead of introducing a company the homeowner has never heard of. That turns a cold touch into a warm touch.

Setting up that first touch in GlassHouse takes three steps.

1. Choose the area you want to canvass.

You can target homeowners within the neighborhoods and ZIP codes you choose, or draw a custom shape on a satellite map around specific streets or a storm-affected area. Your existing customers appear as green pins, so you can see where you already have a presence.

2. Filter for the homeowners you want.

You can filter the area by home age, home value, home size, lot size, last sale date, and income level. You can see how many homes match your filters before you reveal them, so you only pay to reach the homeowners who fit the jobs you want to win.

3. Send a personalized text.

You can start from our message templates for roofing companies, and our customer success team helps write your first campaigns. For example, after a hailstorm, you can draw shapes around the affected neighborhoods the night before and schedule a message like this to go out at 9 a.m. on the morning your reps head out.

By the time your reps reach the neighborhood, the homeowners have already heard from your business.

Send reps to the homeowners who replied

Replies appear in your GlassHouse sales board with real-time SMS and email alerts. Your team can respond directly, or JackieAI, our AI autoresponder, can reply to homeowners and book appointments.

Below is a real exchange from one of our roofing clients’ outreach campaigns. 

From there, you can push the lead into the CRM you already use, such as ServiceTitan, AccuLynx, or HubSpot, as a new lead record. Your reps can then plan their day around homeowners who have already shown interest, which means less time knocking on doors that won’t turn into leads.

Reach homeowners your reps can’t

Texting reaches homeowners your reps can’t, including those who weren’t home when a rep came by and those in neighborhoods where door-to-door sales are restricted. A text arrives within minutes of being sent, on a device most homeowners check throughout the day, so they can reply when it’s convenient for them.

We also work to make sure your text messages are seen. Carriers filter the texts that pass through their networks and can block messages that look like spam. GlassHouse helps your texts get delivered by registering your number and campaigns with the carriers, reviewing your messages against carrier requirements, and personalizing each text to the homeowner. We also confirm homeowner contact information is accurate, so you aren’t spending your marketing budget on texts that get blocked or go to the wrong number.

Plus, we consult with a national law firm that specializes in the Telephone Consumer Protection Act (TCPA) to keep your campaigns compliant, and we scrub contacts against national and state Do Not Call lists. You can read more in our post: Is Cold Texting Illegal?

Turn one completed job into more appointments

Your crew is on the street for days before leaving a new roof, and the neighbors notice. GlassHouse lets you message the homeowners around a completed job while your crew is still in the area.

In GlassHouse, your customers appear as green pins on your map, so you can see the qualifying homes nearby. You can send them a message like “We just finished a roof on Elm Street and noticed several homes nearby with similar shingle wear. We’d be happy to stop by for a free inspection while we’re in the area.” Mentioning the job gives homeowners a local reason to trust you. You can also leave existing customers out, so you’re not messaging someone you just sold to.

See which neighborhoods produce signed jobs

To make the most of your campaign budget and your sales reps’ time, track which neighborhoods produce signed jobs. GlassHouse runs a matchback to connect your outreach to closed revenue. You upload your list of closed jobs, and we match those homeowners against everyone your campaigns reached. A match shows that a homeowner you reached later signed a contract.

The matchback can also capture jobs from homeowners who received your text and later called your business. Those jobs may be credited to another channel in your CRM. Without a matchback, your outbound campaigns can look like they’re producing less than they are.

With that data, you can send your reps to the neighborhoods that are producing signed work and stop spending time on the ones that aren’t.

Additional strategies to make your sales team more cost-effective

In our experience, GlassHouse works best alongside your existing ads, canvassing, and referral programs. Our roofing clients typically put 10 to 15% of their marketing spend toward outbound text, and the warm touches it creates raise conversion rates across their other channels.

Here are a few other ways to get more from your sales team:

Run Google Local Services Ads and keep your Google Business Profile up to date

Google Local Services Ads (LSAs) appear at the top of search results when homeowners search for terms like “roofer near me.” Unlike standard Google Ads, you pay when a homeowner contacts you through the ad, not when they click. Google ranks your ad based on factors like your reviews, your distance from the homeowner, and how quickly you respond to leads.

A complete Google Business Profile with recent reviews also supports your outbound campaigns. That's because some homeowners who get a text from your company will search for your business and call you instead of replying.

Plan your canvassing separately for storm work and retail replacements

Storm work depends on timing. After a hailstorm, the roofing companies that reach affected neighborhoods first often win the work, so same-day channels like canvassing and outbound texting fit well. Retail replacements usually come from homeowners with aging roofs, and that demand exists year-round, so steady campaigns targeting older homes tend to fit better. (For tips on getting more out of your canvassing team, see our post on door knocking techniques.)

Ask past customers for referrals

Leads from referrals often close at higher rates than shared leads from aggregators like Angi and HomeAdvisor, because those homeowners started the conversation with your business. Asking satisfied customers for a referral and a review after a completed job helps both your referral pipeline and your Google Business Profile.

Track cost per lead, close rate, and customer acquisition cost by channel

Once you can attribute leads to their source, three metrics show which channels deserve more of your budget:

• Cost per lead (CPL): What you pay, on average, for each lead a channel produces.

• Close rate: The percentage of leads from a channel that turn into signed jobs.

• Customer acquisition cost (CAC): Your total spend on a channel divided by the number of new customers it produced.

Reviewing all three together, rather than any one of them alone, gives you a clearer picture of which channels to scale up and which to pull back on.

Next steps with GlassHouse

In our experience, GlassHouse works best for roofing companies bringing in $5 million or more in annual revenue that are already running a canvassing team, ads, or referral programs. Our roofing clients typically put 10 to 15% of their marketing spend toward outbound text, and use it to make the channels they already have more cost-effective. 

Our roofing clients have seen strong results from adding outbound text to their sales process:

• A roofing and construction company in Washington generated $217,294 in revenue from June to September 2026. They texted homeowners in the neighborhoods around their job sites, and eight of the homeowners became customers, at an average ticket of $27,161.75.
  
  

• A roofing and siding company in Grand Rapids, Michigan, signed two jobs at $25,700 each in their first three months, from August to October 2026, for $51,400 in revenue.
  
  

• A roofing company in Shreveport, Louisiana, generated $512,045 in revenue from April to October 2026. They texted homeowners consistently over those seven months, and 31 homeowners added to their CRM signed contracts, at an average ticket of $16,517.58.
